Summary
Crosses were made between strains carrying a nuclear control factor (NC) and strains classified with respect to their omega allele (ω+ or ω-). The characteristic asymmetrical transmission was always observed (as was seen) in crosses not involving the ω factor. The analysis of functional recombinants in a cross involving an NC factor has indicated that the absence of the ω effect may be caused by a restriction in the zygote of the recombination of mitochondrial DNA molecules.
